\ SPECIFICATION forming part Of Letters Patent NO. 340,197, (Slated April 20, 1886. Application filed January 15, 1885. Serial No. 152.954. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN D. CURTIS. a citizen of the United States. residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Machinesfor Twisting and Spooling lVire Strands; and Ido hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to machines for twisting together two or more wires or wire strands and winding the same upon a spool or reel; and it consists in certain novel features of construction, as will be hereinafter fully set forth and described, whereby, by a single revolution of the twisting-machine, a number of twistswill be put into the wires.

Referring to the drawings making a part of this specification, Figure 1 represents a top or plan view of the machine, with the spoolframe shown in two positions by full lines and dotted lines, as will be hereinafter explained. Fig. 2 is a side view of the parts of the ma chine shown by full lines in Fig. 1, looking in the direction of the arrow, same figure, and showing, in addition, a small guide Wheel or pulley supported above the machine, over which the wire passes before it enters the machine to be twisted and spooled, as will be hereinafter described; and Fig. 3'represents a vertical longitudinal section through the machine on line or m, Fig. 1, looking in the direction indicated by the arrow, same figure, the rotating frame being turned around in this figure, so as to be upon a line with the driving-shaft.

Similar letters of reference refer to similar parts in the drawings.

In the accompanying drawings, the part marked A represents the base of the machine. It may be made of a hollow casting, instead of solid, as shown in the drawings, and secured to the floor in any suitable manner. The several parts of the machine are arranged and secured in and upon the base part A.

The part marked B is a revolving frame or flier of substantially the form shown in the drawings, arranged to revolve around on the base part A in either direction, being secured at its central part tothe upper end of a vertical spindle, C, a collar, a, being interposed between the top part of the base A and the lower part of the flier B, as shown. The frame B is provided with two small loose friction wheels,-b b, which tend to support and steady the frame B as it is turned around on the'base A by means of the spindle 0 being revolved, which spindle turns in a bearing in the base part A, having a large beveled gear, D, keyed to its lower end, as shown in Fig. 3, which meshes with and is operated by the beveled gear G, secured to the end of the driving-shaft H, which in this instance is driven by a belt passing around the pulley I, secured to the driving-shaft H, as shown, the base A being cut out to receive the gears D and G.

Upon the upper part of the base A is secured a beveled toothed ring, J, for the pur- 7o pose to be hereinafter stated.

The part marked K is the spool-frame,which is arranged to turn in bearings c c in' the upper part of the flier B, the journals (1 (1' projecting out from the spool-frame K through the bearingsc c, the journal cl being hollow or tubular, to allow the wires to pass through to thereceiving-spool. Thespool-frameKmoves or is carried around with the revolving flier B.

It also revolves or is moved around upon its own axis by means of the spur-gear e, secured upon thejournal (1, being driven by a system of small gears, f, g, h, and i, arranged upon one end of the flier B, in connection with a small beveled gear, j, which meshes with the beveled ring J, as shown in Figs. 3 and 2. The revolution of the flier B carries around the spool-frame K, and also causes the said spoolframe K to be revolved upon its own axis in the manner above stated, and fully illustrated 0 in the drawings.

In the spool-frame K is supported the receiving spool or reel L upon which the twisted strand is wound. Said spool L revolves with the spool-frame K,'and also has a motion of 5 its own, to take up andwind the strand, the axis of revolution of the spool L being at right angles to the axis of revolution of the spoolframe K. The spool L is operated to take up the twisted strand in the following manner: rco The spool is supported upon and turns with the removable spindle k, the ends of which,

gear 19 is driven by means of a belt, q, passing around a stationary pulley, q, secured to the base part A, and also around grooved pulley r, secured to a vertical shaft, 8, turning in hearings in the flier B, beveled gears t and u, and spur-gears o and to, all as clearly shown in the drawings.

The provision for the intermittent feeding of the wires to the twisting and spooling ma- V chines is essential and necessary for the proper working of my machine; for my twister and spooler is designed especially to be used in connection with machines for barbing wire of the usual and well-knowu construction, in which the main wires are fed through the machine intermittently, to allow of the barbs being coiled upon the wire between the intervals of feeding forward the main wires. Consequently there must be some provision in the take-up mechanismorinthetwisteraudspooler to allow for this intermittent feed through the barbing-machine. In my machine I have provided for this by means of the coiled spring 0, above described. \Vhen the spool L is prevented from turning, the feeding forward of the wires to the same being stopped as the barb is being applied to the wire or wires, the mechanism lor turning said spool continuing to operate expends itself on the spring 0, causing the same to coil or wind until the main wires are again fed forward, releasing the spool L and allowing it to revolve, when the tension of the spring, 0, re turning to its normal condition,will cause the spool L0 revolve faster, and thus take up any extra slack. In this instance the strand is evenly distributed over the surface of the spool from one end to the other, as it is wound thereon, by passing over a sprocket-wheel, M, which is moved back and forth laterally upon a horizontal shaft, N, having a right and left hand thread cut therein in the usual manner, by revolving or turning the shaft N, supported in suitable bearings in the spool-frame K by means of a belt passing around a grooved pulley. O, secured to and turning with the shalt N, and a grooved pulley, P, secured to and turning with the spool-spindle k, as clearly shown in Fig. 1.

Upon the end of the flier B is arranged to turn a small sprocket-wheel, Q, around which the wire passes before passing through the hollow journal d of the spool-name K to the spool L.

Above the machine is supported in any suit able manner a sprocket-wheel, R, over which the wires pass before entering the twisting and spooling machine to be twisted together and wound upon the receiving-spool.

The operation of my machine is as follows: The wire or wires from the barbing machine or the delivery-machine are first passed over the sprocket-wheel R and then around the sprocket-wheelQ. through the hollow journal d of the spool-frame K, to the receiving spool or reel L, the end or ends of the wires being secured thereto. The driving-power of the machine being put in motion, the flierBis revolved around on the base A in the manner before stated, and carries around with it the spool-frame K. By this motion one twist is put into the wire or wires between the delivery-machine and the point where the wires enter the machine. As the flier B revolves around upon the base A, carrying with it the spool-frame K, said spool-frame K also revolves in its bearings in the upper part of flier B upon its own axis, (which is at right angles to the axis of revolution of said flier 13,) in the manner previously described, (see full lines and dotted lines, Fig. 1,) imparting a twist to the wires every time the spoolframe K revolves upon its own axis, in addition to the twist previously put in the wires by the revolution of the flier B, as above stated. As the tlier B and the spool-frame K revolve and twist the wires the receiving spool or reel L takes up andv winds thereon the twisted wires, being operatedin the manner previously described.

The number of revolutions of the spool,- frame K on its axis may be varied relatively to the number of revolutions of the flier B upon its axis by changing the size of the gears for operating the spool-frame K.

the manner of construction of the several parts of the machine as shown in the drawings, nor to the means for operating the same as shown and described, as they may be changed and varied therefrom without departing from the principle of-my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with flier B and spoolframe K, and means for rotating said flier and frame, substantially as described, oi the spool L and means for rotating the same, substantially as described, to allow of the intermittent take-up of the material, substantially as set forth.

2. The combination, with flierB and spoolframe K, and means for rotating said flier and frame, substantially as described, of the spool L, bevel-gears Z and m, spring 0, and

substantially as described, and for the purpose stated.
